A knife has been recovered at a California estate once owned by former football star O.J. Simpson, who was cleared of murder charges more than 20 years ago in the killings of his ex-wife and her friend. According to Los Angeles police spokeswoman Norma Eisenman, it's not known when the knife was discovered or whether it is related to the 1994 deaths of Nicole Brown Simpson and Ronald Goldman. At one point during the high-profile murder trial, Allen Wattenberg, owner of Ross Cutlery store, testified that an employee sold Simpson a 15-inch stiletto knife on May 3, 1994. He added in his testimony that Simpson wanted the knife to be sharpened.Posted By Ghost
